Electric charger standardization remains question, hurdle in Europe's EV adoption



The electric vehicle charging-station standardization issue that's viewed as a major hurdle to mass EV adoption goes far beyond SAE vs. CHAdeMO, apparently. European nations are also divided about which standard the European Union should use in its effort to build out the infrastructure necessary to ease away-from-home charging of plug-in vehicles, Ward's Auto reports, citing auto industry analysts at a Brussels conference.

Specifically, most European auto makers and auto suppliers are standing behind the Type-2 charging system backed primarily by Germany just as the European Commission starts an impact assessment for charging infrastructure, according to Ward's. Meanwhile, France is backing the Type-3 system, as Type-2 lacks a so-called "shutter" cover that's supposed to help prevent electrocution.

The issue is a major one as automakers such as France-based Renault look to spur plug-in vehicle sales, which have been slower than expected. Meanwhile, the UK has about 1,000 charging stations, while France has about 1,300 and Germany and Spain each have almost 900.

As it is, automakers from Japan are promoting a different on-board charging standard than one backed by European and US automakers. Nissan, Toyota and Mitsubishi are supporting the CHAdeMO standard, which was launched in 2010 and is used in 1,500 stations worldwide. US and European automakers like BMW, General Motors, Ford and Volkswagen are standing behind the less-established SAE Combo standard, which is being promoted as simpler since it requires just one charging port for standard- and fast-charging connections.

SAE International releases new fast-charging combo coupler standard (SAE J1772) for plug-in electric and electric vehicles


SAE International’s anticipated new revised technical standard for the combo coupler for plug-in hybrid electric vehicle (PHEV) and electric vehicles (EV) has been approved and published.
Developed in a consensus environment by more than 190 global experts representing automotive, charging equipment, utilities industries and national labs, “J1772: SAE Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Couple” enables charging time to be reduced from as long as eight hours to as short as 20 minutes.
This new standard reflects the many hours that top industry experts from around the world worked to achieve the best charging solution— a solution that helps vehicle electrification technology move forward. We now can offer users of this technology various charging options in one combined design
—Gery Kissel, Engineering Specialist, Global Battery Systems, GM, and SAE J1772 Task Force Chairman
The original version of J1772 defined AC Level 1 and AC Level 2 charge levels and specified a conductive charge coupler and electrical interfaces for AC Level 1 and AC Level 2 charging.
The new revision incorporates DC charging where DC Level 1 and DC Level 2 charge levels, charge coupler and electrical interfaces are defined. The standard was developed in cooperation with the European automotive experts who also adopted and endorsed a combo strategy in their approach.
